Hi, I'm running:
OpenBSD victim.blackhelicopters.org 7.2 GENERIC.MP#640 amd64 According to mount_ntfs(8), -u and -g let you set UID and GID of mounted filesystems. Took an NTFS USB drive, plugged it in, mounted it, and checked ownership. # mount_ntfs -u mwlucas -g mwlucas /dev/sd4i /mnt/ # ls -lai /mnt/ total 107 4 -rwxr-xr-x 1 root wheel 2560 Dec 31 1600 $AttrDef 8 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $BadClus 6 -rwxr-xr-x 1 root wheel 32768 Dec 31 1600 $Bitmap 7 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $Boot 11 drwxr-xr-x 1 root wheel 0 Aug 17 15:05 $Extend 2 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $LogFile 1 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $MFTMirr 9 -rwxr-xr-x 1 root wheel 0 Aug 17 15:05 $Secure 10 -rwxr-xr-x 1 root wheel 131072 Dec 31 1600 $UpCase 3 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $Volume 5 drwxr-xr-x 1 root wheel 0 Dec 31 1600 . 2 drwxr-xr-x 15 root wheel 512 Aug 16 13:02 .. 36 drwxr-xr-x 1 root wheel 0 Aug 17 15:05 System Volume Information 38 -rwxr-xr-x 1 root wheel 111496224 Aug 17 13:35 VirtualBox-6.1.36-152435-Win.exe If I create /tmp/mnt owned by mwlucas:mwlucas and mount there, ownership of the mount point is changed to root:wheel and the files are owned by root. # chown mwlucas:mwlucas /tmp/mnt ls -lai /tmp/ total 1 2 drwxrwxrwt 9 root wheel 512 Aug 17 15:42 . 2 drwxr-xr-x 15 root wheel 512 Aug 16 13:02 .. 25920 drwxrwxrwt 2 root wheel 512 Aug 16 13:02 .ICE-unix 388800 drwxrwxrwt 2 root wheel 512 Aug 16 13:02 .X11-unix 77760 drwxr-xr-x 2 mwlucas mwlucas 512 Aug 17 15:42 mnt 259200 drwxr-xr-x 2 root wheel 512 Aug 16 13:02 sndio ... # mount_ntfs -u mwlucas -g mwlucas /dev/sd4i /tmp/mnt/ # ls -lai /tmp/mnt/ total 107 4 -rwxr-xr-x 1 root wheel 2560 Dec 31 1600 $AttrDef 8 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $BadClus 6 -rwxr-xr-x 1 root wheel 32768 Dec 31 1600 $Bitmap 7 -rwxr-xr-x 1 root wheel 0 Dec 31 1600 $Boot 11 drwxr-xr-x 1 root wheel 0 Aug 17 15:05 $Extend ...
